Double-drum soil-sieving harvesting device

Abstract

The invention relates to the technical field of agricultural harvesting machinery and discloses a double-drum soil-sieving harvesting device. The double-drum soil-sieving harvesting device comprises an excavating and soil breaking wheel, a collecting shovel, a rack, a collecting spiral and two conveying separation mechanisms, wherein the conveying separation mechanisms are mounted in parallel on the rack at the same tilt angle f; the excavating and soil breaking wheel positioned below the front parts of the conveying separation mechanisms is rotationally connected to the rack; the collecting spiral positioned above the rear parts of the conveying separation mechanisms is mounted on the rack; the collecting shovel positioned at the rear part of the excavating and soil breaking wheel is fixedly connected to the rack; a soil mixture excavated by the excavating and soil breaking wheel is collected through the collecting shovel and distributed to feeding spiral sections of the conveying separation mechanisms; soil is separated by the conveying separation mechanisms; materials subjected to soil removal are output by the collecting spiral. A double-parallel-drum-sieve soil separation mode is adopted; the instant separation area of unit cubic metre of earth is increased to realize sectional type mechanized efficient harvesting operation of excavation, collection, double-spiral conveying, double-drum soil sieving and strip laying of cyperus esculentus.

Description

technical field [0001] The invention relates to a double-drum sieve soil harvesting device, which belongs to the technical field of agricultural harvesting machinery, and in particular to a double-drum sieve soil harvesting operation equipment for oily beans. Background technique [0002] The origin of oily bean is Africa. It is a high-quality and high-yield oil crop and belongs to the annual plant of Gramineae. It can be planted on beaches, hillsides, hills, and forests in the north and south of my country. It is resistant to drought and waterlogging, and is easy to grow and manage. The grass grows on the ground, up to 100-120cm high, with fibrous roots, strong tillering ability, growing in clusters, flat and thick leaves, slender and sword-shaped, with a yield of more than 3000kg of fresh grass per mu. It is suitable for raising cattle, sheep, High-quality feed for fish, rabbits and geese. Youshadou mainly harvests underground nuclear rhizome fruits, which are suitable f...
